This claim no longer has scientific support. Sugar is fuel of the body engine. When the butcher's daughter, Gertrude Ederle, failed in her first attempt to swim the English Channel, she very justly charged her collapse before reaching the English shore to the mutton stew her trainer gave her before starting. When in a second attempt, she adopted my suggestion through a mutual acquaintance, to eat sugar instead of meat, she made a world record. This practice is, I believe, now adopted by all successful channel swimmers. Non-flesh eaters are far superior to meat-eaters in endurance under special strains. When Dempsey defeated the Argentinean giant, he had trained on modest allowances of meat and his last meal had consisted of vitamin-rich fresh vegetables, while Firpo loaded himself up with steaks and chops. When Battling Nelson lost his championship, he explained to a newspaper reporter, "'Twas the beefsteak that done it. I swiped an extra beefsteak when my trainer was not looking, and it made me tired." De Lesseps, the famous French engineer, became a confirmed and enthusiastic flesh abstainer when he found his sturdy beef-fed Englishmen could not compete in work on the Suez Canal with the Arab laborers, who subsisted on wheat bread and onions, as did the builders of the pyramids, according to Herodotus, 5,000 years before. He declared, in fact, that without the hardy Arabs, he could not have done the work. Theodore Roosevelt, in his story of his East Africa hunting expedition, said in Scribners Magazine that a horse with a heavy man on his back could always run down a lion fleeing for his life in a mile and a half. Claim 4 That a man can live on a flesh or muscle meat diet such as chops and steaks. The famous pedestrian, Weston, informed me that on his long walks, he never ate meat and on his walk across the continent lived on corn flakes and milk. Carl Mann, a grocer's clerk not professionally trained, competing in a government supervised walking race from Dresden to Berlin, 123 miles, against the picked pedestrians of the German army and several professionals, won easily on a fleshless diet consisting of nuts and fresh vegetables which he pulled out of the vegetable gardens as he hurried by. The only protein he ate was derived from nuts. The Tarahumari Indians of Mexico are the most tireless runners in the world. Their ancestors were the dispatch runners of Montezuma in pre-Colombian days, and they still adhere to the simple plant regimen of their forbears. At the time of the Boxer uprising in China some years ago, the rice-fed Japanese were the first to arrive of the military representatives of numerous nations who raced to the rescue of the foreign embassies besieged by the fanatical and bloodthirsty Boxers. Claim 5 That a man can live and enjoy good health for a year or many years on a purely flesh or muscle-meat diet.
